Oh, the exception was: Software Error: hlds.instmap: predicate `hlds.instmap.merge_instmapping_delta_2'/9: Unexpected: merge_instmapping_delta_2: error merging var 21 Which isn't helpful without a test. |

I can cause the compiler to crash using bug300.m and the following command: mmc --java --optimize-constructor-last-call bug300 |

I've found the problem, LCMC wasn't processing from ground term scopes properly. I'll test this properly and post my changes for review shortly. |
